Personalized Body Weight Management System Using Monitoring Devices and Mathematical Models of Metabolism

Description of Technology: Attempts to manage body weight are often unsuccessful or only temporary. This is, in part, due to antiquated dieting methods that attempt to address calorie consumption while ignoring metabolic and physical changes. It is becoming clear that personalized methods to manage body weight must be developed.

Scientists at the NIH have developed new methods for prescribing and monitoring personalized weight management interventions. The system uses validated mathematical models of human metabolism to set weight management goals and predict individual body weight outcomes in the context of changing metabolic needs and calorie consumption. The system uses repeated monitoring of a patient's body weight to assess progress and provide specific feedback to the patient and health care professional. Projected outcomes and body weight goals can be revised over time along with required prescription modifications to meet the body weight goals. The system is integrated into a network of one or more devices that may additionally monitor various physiological parameters, physical activities, food intake, or other behaviors. Such an enhanced personalized weight management program has great promise in the management of obesity.

Potential Commercial Applications:

  • Devices—Weight management diagnostic.
  • Software for the integration of multiple devices.

Competitive Advantages: Integrated system provides feedback to health care professional and patient with more accurate predictors of weight loss outcomes. Combined with other devices, patient receives encouragement to stay on track.

Direct Impact Spark Ionization (DISI) Mass Spectrometry (MS) for Identification of Microbes

Description of Technology: Generating reproducible mass spectra from bacterial samples in a timely fashion at atmospheric pressure remained problematic for many years. FDA/NCTR inventors designed a rapid mass spectrometry device using direct impact spark ionization source for microbial analytes identification via spectral pattern recognition. The device design includes a rapid mass spectrometer suitable for analyzing microbiological samples that was earlier used to analyze low volatile organic compounds. The device employs a solid needle for electrode discharge. It includes a gear plate that introduces stainless steel pins carrying bacterial samples. The pins also act as counter electrodes and are targeted by controlled arcs. The small custom-made glass cylinder that is meant to shut out oxygen and prevent the introduction of ambient moisture into the analyte is unique from other DISI device. The examination revealed enormous peak intensity and spectral information with normal ionization mode on the same instrument. This device can be employed in fields such as pathogen determination in clinical settings, QA/QC (of drugs, food or cosmetic ingredients), continuous monitoring of (airborne) Biological Warfare Agents and the like.

Potential Commercial Applications:

  • Pathogen detection,
  • QA/QC (of drugs, food or cosmetic ingredients),
  • Continuous monitoring of (airborne) Biological Warfare Agents and the like.

Competitive Advantages:

  • Rapid, specific, sensitive and reproducible identification of microbiological analytes.
  • Systematic acquisition of reproducible spectra among same bacterial species.
  • Whole cell analysis of food-borne pathogens is rapid, safer and micro-reliable.
  • Characteristic mass spectra obtained and reproduced for food-borne pathogens.
  • Unique DISI device with gas cylinder chamber.

Development Stage:

  • Prototype.
  • In vitro data available.

Method of Treating Hepatitis C Virus Infection With a Small Molecule CHK2 Inhibitor

Description of Technology: DNA damage sensors such as Checkpoint Kinase 2 (Chk2) are key regulators of the cellular DNA damage response that limits cell-cycle progression in response to DNA damage. It has been reported that these DNA damage sensors also play a key role in Hepatitis C virus (HCV) replication. The subject technology are small molecule CHK2 kinase inhibitors that have been shown to have promising activity against HCV replication. The compounds were discovered by high throughput screening of chemical libraries with more than 150,000 compounds. These novel compounds can potentially be used in combination with other anti-HCV drugs or interferon and represent a novel target for treating HCV. In vitro antiviral assay data, as well as preliminary in vitro and in vivo pharmokinetic data are available upon request.

Potential Commercial Applications: The subject technology can potentially be developed into anti-HCV therapeutics, particularly in combination with other anti-HCV therapeutics.

Competitive Advantages: The subject technology represents a novel and promising target for treating HCV infection and thus, has the potential to increase the efficacy of other HCV antivirals that directly target HCV in a multi-drug formulation. Furthermore, since the subject technology targets a cellular protein necessary for HCV replication and not the virus itself, the emergence of viral resistance against the subject technology could be low or more delayed.

Development Stage:

  • Early-stage.
  • Pre-clinical.
  • In vitro data available.
  • In vivo data available (animal).
